Breakwater Rock marks the eastern boundary of Merri Marine Sanctuary in Warrnambool, western Victoria. This rocky headland juts into the cold, oxygen-rich waters of the Southern Ocean, where calcarenite reefs and kelp forests create a vibrant underwater playground. Snorkelers can explore the rocky gutters and boulder fields adjacent to the breakwater, drifting over colourful sponge gardens, crayfish crevices, and swaying kelp. The site offers a raw, wild experience typical of Victoria's Shipwreck Coast — clear water, abundant sea life, and the dramatic energy of the Southern Ocean swells.

Moderate risk: Strong currents and undertows
Powerful Southern Ocean currents and undertows run along the rocky headland, especially during tidal changes.
Moderate risk: Large unexpected waves
Swells from the Southern Ocean can send large rogue waves over the rock platform without warning.
Moderate risk: Sudden weather changes
Western Victoria's coastal weather can shift rapidly from calm to dangerous conditions with strong winds.
Low risk: Slippery rock platforms
The intertidal calcarenite rock platforms are coated in algae and become extremely slippery when wet.
Low risk: Cold water temperatures
Southern Ocean waters are cold year-round (10-16°C), requiring a thick wetsuit for comfort and safety.
